Abstract

Query expansion, while generally effective in improving retrieval performance, may lead to the query-drift problem. Following the recent development of applying Quantum Mechanics (QM) to IR, we investigate the problem from a novel theoretical perspective inspired by photon polarization (a key QM experiment).
